Specification of Ilteissued Letters Patent. Reisgued Mar, 11. 1919.

Original No. 1,289,736 dated June 18, 1318, Serial No. 182,270, filed July 23, 1917. Application for reissue i filed November 1, 1 818. Serial-No. 260,754.

To all whom it may concern:

Be it known that I, ivicumr l i nsiinr PAnMnN'ricu, a citizen of the United States'of America, residing at Redford, in the county of lVayne and State of hlichi an, have invented certain new and useful Improvements in Power-l rames, of which the following is a Specification, reference bci had, therein to the accompanying drawings.

lhis invention relaces to a power .lfranie and has for its object the product-ion of a simple and efiicient power frame which is adapted to be used in connection witch automobiles or other. motor vehicles whereby power may be obtained and lllilllSHillLlBtl fron'rthe rear drive wheels oi. ijil'fi nioior vehicle.

Another object of this invention is ie production of a simple and etlicient po ier frame which. is light in construction and upon which may be easily and eliicienitly attached a saw 'i'rame or other machine which. is adapted "to i be driven :lro:n the drive wheels of amotor vehicle.

lV ith these and other objects in VlOW. this invention consists of certain novel construcof parts as will be hereinafter fully described and claimed.

In the drawings:

Figure l. is a side elevation of the power attachment, shown cooperating with the drive wheelsof a moior vehicle.

Fig. 2 is a central, longitudinal scclion ot' the power frame shown connected to an automobile the drive axle thereof being shown in. section.

Fig. Sis a side elevation of an automobile,

the rear axle being shown in section, the power frame also being shown in a position ready to lift the rear axle and move the drive wheels out of engagement with the ground.

Fl". L is a to) ilan View of the iowcr' is a section taken on line 5-5 of line S-8 of Fig. 9 is a detail fragmentary, perspective view of one corner of the power frame.

Fig. 10 is a detail perspective of one corner 01% the machine frame which is adapted to rest upon the power frame.

lly referrina toihe drawings it, will be seen that 1 designates the body of the automobile which is provided with. the usual rear drive axle This axle supports the usual rear drive wheels A power frame is adapted to cooperate with the rear axle 2 of the automobile 1 and this frame comprises a pair of bottom rnnners r. The runners are of channel iron construction and are provided with upwardly curred foiwvard ends 5 as shown clearly in. Figs. and 3.

These runners fil are adapted to be arranged in spacel'hparallel relations, and each runner carries a strap plate 6 upon the top edge thereof as shown clearly in Fig. 6 of the lrawings. These strap plates 6 are provided with upwardly inclined forward ends.

which forward ends are provided with cradle-sockets 8. .The extremity of these cradle-sockets 8 overhanging the ends 5 as shown in 7 and being riveted or other wise permanently secured to the upper ends of the upturned ends 5. Suitable rivets 9 are employed for firmly holding tnereby plates (3 in engagement with the channel irons 4C.

An endang'zie plate 10 is secured to the rear ends of the strap )latcs G by means of the bolts 11 which pass therethrough and which also extend through the channel. runners i. A transversely extending angle plate 12 is secured to the top of the plates 6 and faces angleplate 10 as shown clearly in Figs. 4 and 5 of the drawings, the angle iron 12 is braced by'zneans oil the angle braces 13 which engage the rear of the angle plate 12.

A power shaft supporting bracket 14: is carried by the upwardly inclined end 7 of each plaic 6 and these brackets 1&- support a power shaft 15. Each bracket 14 is provided with laterally extending feet 16 which feet are provided with elongated apertures 17 for receiving securing boltslS carried by the ends '7. It, should be understood that these brackets 14: may be adjusted to a proper position for holding the lzriction wheels 19 in proper engagement wlth the tires of the wheels 3. These friction Wheels 19 are carriedon' the shaft 15 andiare adapted to fri'ctionally engage the wheel 3 whereby power may be transmitted through, said wheels 19 to the shaft lij from the wheels 3.

The machine frame 20 is supported upon 7 the power frame and may be of any suitable or desired construction without departing from the spiritof thelinventio n. This machine frame 20 isprovided with a plurality of converging, supporting legs which supporting legs are braced at theirlo'wer ends by means of the transversely extending plates 21. These plates 21 fit snugly against the angle plates 101an'd 12. In order that the power frame may efficiently hold thema chine frame against lateral movement, a securing bolt 22 is passed through the aperture 23 formed. in one of the platesf21 and through the aperture 24 formed in the angle plate 10. There of course will be very little lateral strain upoirt-he machine frame 20, and this securing bolt 22 will besuihcient to hold the frame 20 against latelal shifting n'ioi 'ement.

-The frame 20 is provided with a suitable table and a shaft 261s supported upon the top 20 as shown in Fig, 2 of the drawing. This" shaft 26 is adapted to support a 27 as shown in Fig. 1. and a drive pulley 28 is also carried by this "shaft 26, a suitable drive belt passes over't he pulley 28 and also passes over one of the pulleys 30 formed upon oneof the friction wheels 19.

J'Vhen it is desired to operate the sawlor other ,machine mechanisn'i which may be substituted for thesaw, a power frame is placed in the position such as is illustrated in Fig of the drawings in order that the cradle-portion 8 may fitunder the axle 2. After the, frarriehasibeen,placedor forced into the position shown in Fig. 3, the outer cnd oflthe, power frame, may be forced (ilownwardly thereby moving and lifting the 2; upwardly andrelieving the wheels from the ground, thislmovcmcnt possible, du to tl'ierocking action and leverage which is obtained by the power frame when forcing the same, downwardly; The friction whceis lfil 'may bo'ad'justql into frictional.
